NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 624,780, dated May 9, 1899.

Application filed February 8, 1898. Serial No. 669,574. (No model.)

To all whmn it may concern:

Be it known that I, EPHRIAM A. FOSTER, a

- citizen of the United States, and a resident of Port Clinton, in the county of Ottawa and State of Ohio, have invented certain new and useful Improvements in N on-Refillable Bottles; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that class of bottlestoppers which are intended to prevent the use of a bottle a second time without detection, and has for its object to provide a device for that purpose which shall be simple in construction and eifective in practice; and it consists, essentially, in a bottle having an interiorly cone-shaped neck formed with an exterior incision or groove and with an interior flange in the mouth of the neck, in combination with a cone-shaped metallic stopper seated within the cone-shaped stopper, as hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view of a bottle, the neck being constructed in accordance with my invention. Fig. 2 is a longitudinal section through the neck of the bottle. Fig. 3 is a detail view of the cone shaped stopper used.

Referring to the drawings, l designates an ordinary bottle, the interior of the neck 2 of which is cone-shaped to allow for the reception of a cone-shaped stopper 3. This stopper is made of spring metal and has slit 4 extending its length to allow for the contraction and expansion of the same when it is inserted in position, the meeting edges of the stopper overlapping.

If it is desired, the outer face of the stopper may be coated with powdered cork, rubber,

or cement; but the object of the invention is accomplished without this.

The mouth of the neck of the bottle is provided with an interior flange 5, the purpose of which is to prevent the stopper?) from being removed after having been placed in position.

On the outside of the neck,at its most contracted portion and below the cone-shaped stopper, there is an incision 6 to facilitate breaking of the neck of the bottle when it is wanted to get at the contents ofthe bottle.

. A'stopper 7 may be inserted into the neck below the incision 6 before the cone-shaped tract so as to pass the flange 6, when it will expand and tightly fit the cone-shaped seat provided for it. The flange 5 prevents the withdrawal of the stopper, and the only way to get at the contents of the bottle is to break the neck off, which is easily done on account of the incision 6 When once the neck is broken off, the utility of the bottle is de stroyed so far as its use a second time is concerned, though the bottle may be used until its contents are exhausted, as an ordinary bottle.

Having thus fully described my invention, what I claim is- The combination with a bottle, the neck of which is formed with a contracted cylindrical passage at the lower end and the upper end enlarged and made flaring or conical-shaped and formed with an annular flange at the upper end, and said neck formed with an exterior incision at themost contracted portion, of the metallic cone-shaped spring=-stopper formed with a slit extending from the top to the bottom thereof, located in said flaring portion of the neckwith its points extending down into the contracted portion ofthe neck and the large end abutting against said flange and the stopper located on said contracted portion of the neck below the conical stopper,

substantially as described.

In testimony that I claimthe foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
